Description
Summary:A mathematical model of the two-phase three-component filtration of the oil–water–supercritical fluid system in a porous medium is developed. The results of numerical simulations of the three-component two-phase filtration during oil displacement by supercritical CO 2 from a watered stratum are reported. In the region of oil displacement from watered stratum, there is a significant discrepancy between the experimental and simulation results because of the transient mode of filtration associated with the concurrent saturation of the oil and water with supercritical CO 2 under high pressure. In the region of two-phase filtration of the oil–water system and in the region of pumping of three or more pore volumes of supercritical CO 2 , the deviation of the simulation results from the experimental data does not exceed 10%.
